Package change and spinning start-up on empty tubes in a single operation (integrated automation)


When the package has reached the preset yarn length, the spinning position is switched off by the electronic length measurement device. At the same time the operating robot is called up via the machine control system. If additional delta lengths are being used, the package continues to run after reaching the reference length until the robot approaches the spinning position on its control run (advantage: no stationary spinning positions due to full packages). Only then is the spinning position switched off and the change process immediately initiated. The full package is placed on the package conveyor belt in the center of the machine by a robot arm, and at the same time spinning is started on an empty tube (refer to section  Automatic piecing after package change).
